Abstract (en)

[origin: EP3412949A1] A conveyor system, conveyor pipe, and manufacturing method thereof. The conveyor pipe comprises a main pipe (1), pipe connection members (2) respectively arranged at the two ends of the main pipe (1), and a fibrous composite material layer (3) covering the outer surrounding surface of the main pipe (1). The outer surrounding surface of the pipe connection member (2) is provided with multiple protrusions (21). At least a portion of the fibrous composite material of the fibrous composite material layer (3) winds around the main pipe (1) and alternatively hooks around the protrusions (21) of the pipe connection members (2) respectively provided at the two ends of the main pipe (1), so that a pull force in an axial direction is applied to the pipe connection members (2) by means of the protrusions (21). The axial connection between the main pipe (1) and the pipe connection members (2) would be strengthened, thus effectively preventing connection failures caused by insufficient axial forces.
